Hi Loris,
my sd card supplied with the printer never worked irrespective how I formatted it (fat, fat32 etc./ windows/ linux). I took another card (4GB SanDisk) and it worked w/o problems.
As far as I can see reading through the forum there are a lot of people who weren't able to read the (supplied) sd card. The card seems to be very slow and my smartphone doesn't read the card either.

Thanks for your answer Ray !
Unfortunately, It was defective ! (see picture attachement)
So Maybe I'll send it to UK... As I will not started to mount the all kit before 1 or 2 weeks . Or desolder and resolder by myself...

Yes you are right, the 0V pin would not latch in, so replaced crimp pin (last one, I think crimping these pins and sockets is going to be a major hurdle for the successful build and long term reliability for many printers), which did latch nicely.Quote
My fan runs whenever 12V is supplied (not just during heating) - have you checked that the pins from the fan are fully inserted in the housing near the hot end?

Yes, thanks agree and now understand why you run it direct off the 12V supply. Perhaps this should be stated in the commissioning and be an essential check?Quote

Treth - The fan MUST BE RUNNING ALL THE TIME.It's vital for smooth running of the nozzle, as it isolates the heat in the nozzle. Without it, the filament will melt further up, the extrusion pressure will increase, and eventually block. The nozzle mount can melt, and molten filament get stuck in the end of the Bowden tube. Basically, a mess. However, you'll have to take the nozzle apart, but it is recoverable.
I don't understand the "will of course be an open circuit", but you are correct, I guess the electronics for the fan drive provide an exceptionally high impedance (when off!). Now running correctly direct from another power supply plug, thanks.Quote
Fans have low resistance, and are just a coil, so will of course be an open circuit. They need to be connected with the correct polarity. Test it by touching the pins on the 12V input screw terminals, or some other 12V source.
The orientation given in the assembly instruction is correct and works for me.Quote
Also, the fan needs to be mounted on the hot end the correct way around. The fan needs to blow air INTO the heatsink, then the air will come OUT of the cooling nozzles. It's possible that if you put your hand over the back of the fan, you will feel air coming out. This may be just backwash. Check air is coming out of the nozzles.
RepRap supplied looms are great and there was not a single issue with anything there. It is a great advantage that you supply the looms as you do and testing them!Quote
A note on crimps: the hot end connections should all come with crimps on the various parts, they just need plugging into the housing - in the right order. Check the loom-side crimp hasn't pushed out. We do test every single loom! We've been using these crimps and housings for nearly a year, and find them very reliable. There are 4 crimps you have to do on the kit; for the bed thermistor. But you can use any other kind of connector you want, really. Spare a thought for most other printer kit builders; they don't get looms!

Thanks Ian this is a good guide.Quote

You can use our Mendel Tricolour troubleshooting guide for many problems - it will form the basis of the Ormerod troubleshooting guide (which we're working on), as there will be a large crossover between the two. See specifically: [www.reprappro.com]

Thanks Moigy,Quote

Hi Treth,
I had the same issues with the prints not sticking.
Found two causes -
1 - print head too high to start with. I now set by sliding a bit of paper under the print head, fine adjust in 0.1 steps, the paper should drag ever so slightly on the head.
2 - clean the Kapton tape after every print. I use paper tissue and RS solvent cleaner. Wipe dry after to ensure no residue.
Haven't had an issue since following these two points.
